ELISHA \V. CADY, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO DANIEL C.COOPER, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 405,993, dated June 25,1889.

Application filed February 11, 1889. Serial No. 299,535. (No model.)

To all whom it may concern.-

Be it known that I, ELISHA XV. CADY, of the city of Chicago, county ofCook, and State of Illinois, and a citizen of the United States,

have invented a new and useful Machine for Coupling Cars, of which thefollowing is a specification.

My invention relates to improvements in car-couplers, and the objects ofmy improve- Io ments are, first, to provide a bell-shaped buffer-head toguide the link to the pin; second, a swinging pallet to hold the pin upuntil the link presses it back and lets the pin fall through the linkand couple the cars; third,

I 5 the narrow throat of the buffer, which acts as a fulcrum, over whichthe link balances and is held in any position, high or low, as may berequired, by the peculiar shape of the pallet. I attain those objects bythe mechanism illus- 2o trated in the accompanying drawings, in

which- Figure 1 shows the pallet holding up the link, and Fig. 2 showsthe pin resting on the pallet.

5 is the link. 4 is the pin. 3 is the pallet, and

2 is the fulcrum on which the link can oscillate.

- First I use the bell-shape buffer-head to guide the link to the pin.Then I use a swinging pallet to hold the pin up until the link pressesthe pallet back and lets the pin fall through the link and couple thecars.

The butter is made with a narrow throat at the pinhole, which helps tostrengthen the pin and forms a fulcrum over which the link balances whenraising or lowering the outer end, and a larger cavity back of thepin-hole to give room for the link to work up and down, and with arecess back of pallet to allow it to swing back out of the way, so thelink can work up and down when the cars are coupled and running on roughroad.

The pallet is made with a cup, in which the pin sets before coupling,and cannot-be easily displaced by the backing and bumping of the carswhen coupling. The front of the pallet is made of an eccentric shape, sothat when the link is set to receive another car the pallet will pressdown on the inner end of the link and hold it at any angle desired, butnot rigidly, but will yield to greater pressure, all as substantiallyset forth.

I am aware that prior to my invention selfcar couplers have been madewith swing-pallets to hold the pin and with link-guides to 5 5 carry thelink. I therefore do not claim such a combination, broadly; but

hat I do claim is- The combination of the draw-head having a fulcrum 2and a pallet 3, provided with a cup-shaped or concave seat, allsubstantially as described.
